[a, b, c] is a list you built up somehow, and [d, e, f] comes from $(git rev-list master), right? You could go about determining the revision walk boundaries and combine them to set up a revision walk to splice the master line, but what is the point of that? You'll only be painting yourself into a design-corner (you won't be able to do other kinds of filtering), and going around your head to touch your nose. You precisely want list intersection: so write an efficient list intersection in the language of your choice. Why is it a poor man's solution? If anything, your convoluted rev-list solution will probably be more complicated, slower, and bug-ridden. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
